Knife carrier with dovetail guide for a weaving machine for the production of double fabrics

The invention relates to a knife carrier with a dovetail guide for a weaving machine for Production of double fabric, which is cut into two strips by the knife of the knife carrier, consisting of a plate with dovetail grooves arranged in the area of their ends and in the Area of the dovetail grooves arranged, raised in relation to the associated plate surface Sliding surfaces.

So-called pile fabrics are initially produced as double fabrics, which are joined by the pile threads are connected. For cutting the foil threads and Knife carriers are therefore used to separate the double fabric into two mutually independent webs of the type described above, with a dovetail guide parallel to the subject on a assigned guideway are guided back and forth. So that the pile fabric webs have an even surface have, the guidance of the knife carrier must be very precise. In practice, therefore, knife carriers made of cast material, e.g. cast steel used

which both the dovetail grooves and the sliding surfaces are molded. Before using a Such knife carriers must be ground in the sliding surfaces, so that a quiet and safe Guidance of the knife carrier is guaranteed. This not only requires special care during manufacture but also when grinding in. Nonetheless, the service lives of these knife carriers are limited because the sliding surfaces wear out over time.

Guide properties of such a knife carrier. A used knife carrier must be replaced with a new one.

The object of the invention is to improve the running and guiding properties as well as the service life of knife carriers to improve the genus described above.

This object is achieved in that the sliding surfaces are formed on inserts that are attached to attached to the plate.

The use of the insert supporting the sliding surfaces

pieces brings very significant advantages because it initially simplifies the manufacture of the knife carrier vsird. The processing of the knife carrier itself no longer needs to be done with extreme precision, because only the sliding surfaces, which can optionally also be ground in independently of one another, are precise need to be edited. There is also the possibility of insert pieces and! Plate from different Manufacture materials and in particular the plate
